LESS: generate @variables with loops -

I know that using very little CSS classes is possible. I personally used this technique to give another answer.

I am now experiencing the following code:

  @ transparent-black-10: Fade (@Enrow, 0.1); @ Transparent-black-20: fade (@indo, 0.2); @ Transparent-black-30: fade (@ ano, 0.3); @ Transparent-Black-40: Fade (@ Indoor, 0.4); @ Transparent-black-50: fade (@ ano, 0.5); @ Transparent-Black-60: Fade (@ Indoor, 0.6); @ Transparent-Black-70: Fade (@Enro, 0.7); @ Transparent-black-80: fade (@indo, 0.8); @ Transparent-Black-90: Fade (@ Indoor, 0.9); @ Transparent-white-10: fade (@ CBOO, 0.1); @ Transparent-white-20: Fade (@Benko, 0.2); @ Transparent-white-30: fade (@benkoo, 0.3); @ Transparent-white-40: feed (@beccoo, 0.4); @ Transparent-white-50: fade (@ EnglishOn, 0.5); @ Transparent-white-60: fade (@becco, 0.6); @ Transparent-white-70: Fade (@Benko, 0.7); @ Transparent-White-80: Fade (@Benzico, 0.8); @ Transparent-white -990: Fade (@Benjico, 0.9);  

I am thinking that using loop, it is possible to generate lesser variables as above or reject it by language. If possible, do you have some suggestions to generate code more efficiently?
